Price of ONE token: on-chain USD spot price for a single ERC-20 on Base, from the deepest Uniswap v3 pool vs USDC/WETH (slot0), with the pool/fee tier used and its USD depth. No off-chain feed; thin pools are easy to manipulate. To price MANY tokens at once, use multi-token-price instead (one cheaper call).

Price of ONE token: on-chain USD spot price for a single ERC-20 on Base, from the deepest Uniswap v3 pool vs USDC/WETH (slot0), with the pool/fee tier used and its USD depth. No off-chain feed; thin pools are easy to manipulate. To price MANY tokens at once, use multi-token-price instead (one cheaper call).
$0.002Base6calls / 30d - POST/api/contract-read
Generic read-only call to any contract on Base: provide an address and hex calldata (4-byte selector, e.g. 0x18160ddd = totalSupply, optionally followed by ABI-encoded args) and get the raw return data plus best-effort uint/address/bool/string decoding. Read-only (never sends a transaction). Use this for arbitrary view functions not covered by a dedicated tool.
$0.003Base2calls / 30d - POST/api/contract-logs
Recent event logs for any contract on Base over a bounded recent window (reads eth_getLogs). Optionally filter by topic0 (event signature hash). Returns up to 50 logs with block, tx hash, topics and data. Window is limited by the RPC log-range quota. Use this for generic event queries not covered by whale-wallet-tracker or token-deploy-radar.
$0.005Base2calls / 30d - POST/api/wallet-portfolio
Portfolio of a wallet on Base: native ETH plus a curated set of major ERC-20s (USDC, WETH, cbETH, cbBTC, DAI, USDbC), each valued in USD on-chain via Uniswap v3. Returns per-token amounts, USD values and the total.
$0.004Base1calls / 30d - POST/api/base-market-snapshot
BUNDLE: one-call Base market snapshot combining live gas (base fee, priority-fee percentiles, congestion) AND WETH/USDC spot price + gross spread across Uniswap v3 / Aerodrome. Use this when you want both gas and DEX pricing in a single cheaper call; do NOT also call gas-optimizer or dex-arbitrage for the same purpose. Prefer the individual tools only if you need just one of the two.
$0.006Base1calls / 30d - POST/api/aave-yield
Live Aave v3 reserve rates on Base read on-chain: current supply APY and variable borrow APY for any listed asset (default WETH). For yield and borrow-cost bots.
$0.004Base1calls / 30d - POST/api/multi-token-price
Price of MANY tokens (BATCH): on-chain USD spot price for up to 15 ERC-20s in one call, each from its deepest Uniswap v3 pool vs USDC/WETH. Tokens with no pool return an error entry. Use this for 2+ tokens; for a single token use token-spot-price (cheaper).
$0.008Base1calls / 30d - POST/api/pool-slippage
Estimated price impact / slippage for a WETH/USDC trade of a given USD size on Uniswap v3, from on-chain pool depth. Order-of-magnitude signal (v3 is concentrated liquidity), useful for MEV/execution bots before trading.
$0.005Base1calls / 30d - POST/api/token-due-diligence
One-call due diligence for an ERC-20 on Base: GoPlus risk flags, on-chain facts (supply, owner, proxy), and Uniswap v3 pools vs WETH/USDC with quote-side liquidity in USD. Returns objective signals, not a verdict. Replaces three separate calls.
$0.01Base0calls / 30d - POST/api/token-deploy-radar
Newest Uniswap v3 pools created on Base (PoolCreated events) with token symbols, fee tier and block. A new pool does not imply a legitimate token.
$0.005Base0calls / 30d - POST/api/whale-wallet-tracker
Large USDC transfers on Base over the most recent blocks (default ~300), from confirmed Transfer logs: amount, sender, receiver, tx hash, block.
$0.005Base0calls / 30d - POST/api/dex-arbitrage-scanner
WETH/USDC spot price read on-chain from Uniswap v3 and Aerodrome v2 on Base, with the gross spread in bps and which side is cheaper. Fees, gas and slippage are not included.
$0.005Base0calls / 30d - POST/api/token-liquidity-health
Risk flags for an ERC-20 on Base (honeypot, tax over 10%, mintable, unverified source, hidden owner, pausable...) from GoPlus plus on-chain facts (symbol, supply, owner). No safety verdict: no flags is not a guarantee.
$0.005Base0calls / 30d - POST/api/flash-loan-routes
Aave v3 on Base: available flash-loan liquidity and flash-loan fee for any listed asset (default WETH), read on-chain.
$0.005Base0calls / 30d - POST/api/lending-health-factor
Aave v3 on Base: total collateral, debt, health factor and risk band (LIQUIDATABLE / AT_RISK / WATCH / HEALTHY / NO_DEBT) for any wallet.
$0.005Base0calls / 30d - POST/api/contract-profile
Technical profile of a contract on Base: bytecode size, proxy detection (EIP-1167 / EIP-1967 implementation and admin) and owner(). This is NOT a security audit.
$0.003Base0calls / 30d - POST/api/base-gas-optimizer
Live Base Mainnet gas data from eth_feeHistory: latest and 10-block average base fee (gwei), priority-fee percentiles (p25/p50/p75) and a congestion label.
